You're very welcome, backacre. Glad to be able to help.
I've had mixed results with growing Selaginella in the ground. They want some shade, but seem to want more sun than most ferns. I finally got one to continue living through a few seasons (still alive!). It is tucked up under a slight overhang of an old Live Oak tree trunk that I used to plant bromeliads on. In that spot, the Selaginella gets more sun, but still is shaded enough to not fry in our summer heat. They will survive the winter in 8b with a little protection.
